      <p>
        Logisim includes an integrated hex editor for viewing and editing the contents of memory. To access it, bring up a pop-up menu for the memory component (<b class="tkeybd">Right-click</b> on the component ) and select <b class=menu>|&nbsp;Edit Contents....&nbsp;|</b> or in the properties select <b class=propertie>Contents</b>.
      </p>
      <p align="center">

      </p>
      <p>
        The numbers in italics at left display memory addresses, written in hexadecimal. The other numbers display values starting from that memory address; the hex editor may display four, eight, or sixteen values per line, depending on what fits in the window. To help with counting, each group of four values has a larger space between.</p>
      </p>
      <p>
        You can navigate through memory using the scroll bar or using the keyboard (the <b class="tkeybd">arrow keys, home, end, page up, and page down</b>). Typing hexadecimal characters will alter the currently selected value.
      </p>
      <p>
        You can select a range of values by dragging the mouse, <b class="tkeybd">shift-clicking</b> the mouse, or navigating through memory with the keyboard while depressing the <b class="tkeybd">shift</b> key. Values may be copied and pasted using the <b class=menu>|&nbsp;Edit&nbsp;|</b> menu or the associated shortcuts key (<b class="tkeybd">Ctrl-C Ctrl-V,Ctrl-X...</b>); the clipboard can also be transferred into other applications.
      </p>
      <p>
        Two buttons (<b class="button">Open...</b>, <b class="button">Save..</b>) allow you to load or save data from a file.
